Spectroscopic transmission spectra from 1.5 to 200 μm for the Titan 1 COSmIC haze analog (top) and the Exoplanet 2 PAMPRE haze analog (bottom). The simulated absorption-free transmission assuming a constant real refractive index, n, is shown (black curve). The film thickness is fit to match the observed interference fringes in the NIR. The simulated absorption-free transmission spectrum, now accounting for spectral variations in n in the IR (with SSKK model), is also shown (red curve).
